The Frozen Road Period ends and Class II and Posted Roads restrictions begin in Zones 4 and 5 Friday, March 4, 2022, at 12:01 AM CST. The Frozen Road Period remains in effect in Zones 1 through 3.

The frozen road declaration is normally in effect from mid December to late February or early March. Eligibility for increased weight limitations is restricted to vehicles hauling abrasives or salt for highway winter maintenance and peeled or unpeeled forest products cut crosswise not to include woodchips. For legally licensed vehicles hauling these loads, no special permit is required during this period. Legally licensed means currently registered for 80,000 pounds, or the maximum Gross Vehicle Weight (GVW), if less than 80,000 pounds.

Local county or township road maintenance authorities are responsible for determining when local and county roads are frozen or thawing. Questions related to frozen road conditions on local or county roads should be referred to the maintaining authority for those roads.
